    Dear Jim,

    I am using standard 4.6 heads, not ported. I bought the block as a short engine from Chris from RPI. It was a old project that was running once for a short time but the customer didn't finished his project and he kept the engine for himself.
    The pistons have 94mm and on its crown there is a stamp that says .020 so i think they are oversized.
    The crank is a 4.6 but the journals of the conrods have been resized and outcentered and the stroke was increased. It has approximately 4.8 maybe 4.9 now.

    Chris told me the conrods are some special thing and all in all it is a well made bottom end.

    I do not indent to achieve the most possible from this engine, the price for the whole bundle was good, that's why i bought it.
    I plan to use the standard 4.6 heads, all the 3.5 ancillaries, the 3.5 manifold and headers but 2" HS8 carbs to avoid it running lean on higher revs.
    Chris suggested a Piper 270 cam and its already in now.
    The head have springs fitting the camshaft, new rockershaft, new cam followers, ne pushrods, improved oil pump etc..

    Yesterday i bought a complete package of LT77 with bellhousing, remote and stick

    That's the route to go...

    OK for uprating a P6B engine to SD1 spec, but the bigger engines have a crank driven oil pump so the kit you mention is not applicable.

    Dear harvey,
    Thanks for your fast reply. As i use the same timing cover of my old engine and the same oil pump the kit would be applicable to my opinion. Why not?
    Its also driven by the camshaft as before.

    A oilcooler will also be added. Would you suggest a other solution?

    If you use the crank driven oil pump the timing covers do not have a distributor provision, unless you hunt down an intermediate cover which has the crank driven pump but also a distributor hole.
    I built my 4.6 with an SD1 front cover to get the higher volume pump and a distributor, I have an intermediate cover but did not fancy hunting down the different pulleys to go with it.

    Also the SD1 pump base has the more common 3/4 x 16 filter thread.

    Thanks Cobra,

    I understand, but i want to keep my front cover.
    The Kit in the link should be a for a pre 76 engine. As my rover was first registered 76 i dont know about the engine. How could i find out.


    Pre-’76 engines with original short oil pump gears only.
    Kit includes spacer plate and longer gears to uprate early pumps to later specification.
    Increases idle & high RPM pressure. Raises oil volume by 40%

    The distributor drive is opposite on an SD1 to a P6 so if you have an early cover it will have the P6 distributor drive.
    I am resisting describing it as male versus female as it is confusing.

    Regardless of the year your car was registered, if it is a P6B timing cover it will benefit from the kit. 1976 just means SD1 onwards.

    Just a word of warning using the uprated kits. It's difficult to get exact clearances. You may need to swap gaskets or in my case, I machined a fraction off the longer gear.

    Thank you Peter

    Just if you aren't careful you can damage the housing or at the other extreme get less oil pressure than you had before.

    All worked out well.
    The oilpump kit is installed now.

    I also intend to fit a oil cooler for the engine oil.
    Two possible installations could be:
    • Adapter between the oilpump housing and the filter (prefered! if the space allows it)
    • Or do i need a new oil pump cover with fittings vor the oil cooler and replace the oil filter?
    best regards

    If there is not enough room for the adapter, the MGB V8 (these have the Rover V8 fitted) use an external oil filter and these have an oil pump base which can be connected to the front cover. Then a hose runs to the external filter and from the filter to the oil cooler and from the oil cooler back to the oil pump base. MGB V8 part suppliers can supply all the parts needed


    i prefer to use decent hose connections instead of a hose and a clamp
